To aZZ whom t may concern.)-

Be it known that l, CHARLOTTE A. Brame woon, a subject of the liing of Great Britain, and a resident of Westwood, inthe county of Bergen and State of New Jersey, have invented a new and improved Wind- Shield Cleaner, of which the following is a` full., clear, and exact description.

The invention relates to cleaning devices employed for .cleaning the wind shields of power driven vehicles such las automobiles, trolley cars, locomotives and the like.

The object ot' the invention is to provide a new and improved wind shield cleaner ars ranged to enable the driver or operator in' charge of the vehicle to start the mechanism at any time with a view to clean both the inner and outeriaces ot thewind shield. of any accumulated moisture, sleet5 snow, rain, dustt or other' extraneous matter, without stopping the vehicle or.intert'ering with theI Anotherv object is to provide a cleaner which can be readily applied to power-driven vehicles as now generally constructed.

ln order-to produce the desired result,l use is made oi' 'a revoluble screw, a sleeve slid-able on the said screw and having a pin' engaging thefthread of the screw, wiping means attached to the said sleeve andengaging the wind shield to be cleaned, a power driven shaft, and an automatic power driven and reversing gear con';rol1'ed by-the said sleeve anctconnectingl the said shaft with the said screw to rotate the latter alternately inV opposite directions.

A practical embodiment of the invention is represented-in the accompanying drawings forming a part of this specitication, in

which similar characters of reference indicate corresponding parts in all the views. l

Figure 1 is an elevation of the cleaning shield of an automobile, the sides of which are shown in section: Y

Fig. 2 is an enlarged elevation of thi une with parts'sltown in section; l

Fig. 3 is `a transverse section of the same on the-line 3-3 ot'-l"ig.-2:l y

Fig. 4 is a similar view ofthe same on' tl--zof Fig, 2:--

the `line Fig. 5 is a simi!f rivviewbfwtliersame on the line 5--5 of Fig; 2;1r

yfit into the grooves of the -lion 6 is a similar view or the same'on the line 6 6 of Fig. 2; and

Fig. I yis an enlarged sectional plan viewof the Wipers in position onrthe glass plate of the wind shield, the section being on the line l7--7 of Fig. 2.

The glass plate 10 o3 the upper wind'u shield 11, shown in Fig. 1, is provided with theusual frame 12 on which are secured two brackets 13 and l14 provided with bearings for the non-threaded ends 15 and 16 ot`a screw 17 to turn in, the said screw extend-y ing a short distance above the top of the wind shield 11 from nearly one side thereoic` to the other, On the screw rod 17 is mounted to'slide a sleeve 20 provided at its middle with al screw or pin 21 engaging with its inner end ISee Fig. 3) the thread of the screw 17 so t at when the. latter is rotated in one direction a traveling motion is given to the sleeve 20 from the let'tto the right., and when the screw 1 7 is turnedv in the opposite direction thena return traveling motion is given to 'the sleeve 20 to move the latter from the right 'to the left. The sleeve 20 is provided with a depending member 22 fitting th top of the frame 12 of the'wind shield 11 to hold the sleeveY -20 against turning onthe screw 17. To opposite faces of the .depending member 22 of the sleeve 20 are fastened depending arms 23 and 24 to which are fastened wi )ers 25 and 26., preferably made of' rubber, bearing with their freer pieces o ends againstthe opposite faces of the glass plate 10,- las plainly illustrated in Fig. 7. The arms 23 and-24 are yformed with recesses for the reception of the'attaching ends of the wipers 25 and 26, and in order to securelyhold the wipers in place on the' arms `.23 and 24 use is made of drawings 27, 28

fastened by screws 29 and 3.0 to the arms 23. and 24. Stiiieningplates 31 and 32 offsheet metal or similar material engage the outer faces et the wipers 25v and 26 close. up to the i'ree ends of they said wipers to stitien. the latter. TheV stiii'ening plates 31 and 32 ,arms 23, 2l and are fastened in place with the wipers by the action 'of the fastening one Yof the wiping'arms 23. and 24' can be readiiy removed fromv the depending -mfemi' ber 22er the sleeve 20 orrepairsorfothei? bars 27 and 28. Any y as plainly indicated in Fig. l. y

. purposes whenever it is deemed necessary. l

It' is understeod"that,y the wipers 25l and 26-1. extend vnearly V:througho'ut theentijre iheight A of the glassplatelO and'when the sleeve 20 j is moved from theleftto the right and baek again then the/Wipers' 25 and 26 simultaneously clean both faces of the glassplatemlo.

In order to imparta rotary mbtion "to the soreiv 17 5 the' following arrangement is made: 4Oiifth'e'jrigiilliand vside of the nonthreaded Aportion 16 of' the v screw '17 are mounted to 4:rotate loosely-bevel gear "Wheels 40 and 4l/,arranged 'Within a housing 42 formed onthe lbracket 14. The bevelgear Wheels andA4 41are'inmesh with'diametrica-llyoppesite sides of a bevelgear Wheel 43 secured on-a flexible shaft 44 connected with the shaft of a motor 45, preferably of the electriet'ype, and mounted on the antoniobilefat-anyf desired -place thereof. The elec triefim-otor'li iscontrolled by a push button" 46,;'preferably mounted on the steering- Wheel 47 ofthe automobile so as to bef'W'ithin convenient control ot' the driver of the automobile,

Thebeveb gear Wheels 40 and 41;are provided von their opposite faces with clutch members50 andy l adapted to be engaged by clutch'.- members 52` and- 58 vof a double clutch 54' mounted on the-noirthreaded por tion l16- joi thescrew 17A-intermediate -the bevel gear Wheels 40 fand 41;.vv The doubloclutchv member 54 is provided withiscrews or-pins' -passing-throu-ghfa slot 56 formed lengthwise 'in `the non-threaded portion 16 of the screw '17; *By =the larrangement described the double clutch member 54 lis mounted to '-slidedengthwise on the'nonthreaded; 'portion '16 Aand when rotated it turns the `screw 17 owing tothe pin 55 ex. tending through the slot 56. y

Inordervto--shift th'evdouble clutch members4 `from -the right to the left or vice versato enga-ge theclutch members 52 with theveliutch members 50 or the clutch members 53 vithfthe clutch members `51,'the followiniarrangement lis'made: The screw 17' e hollow and in itis-mountedto lslide a shifting-.rod fto whichthe inner ends of theipins 55am-secured, as plainly shown' in Figs.'2.andv4. The shifting rod GO ispro- ,vi'deduwith 'arms' 61 and 62 extending throughslotsf a-nd'64 lformed' lengthwise on thenonfthreaded yportions '16 and 4150it thescrew l17. The arms 6l-andv62 are l0- cated.z adjacentzthe ends of the thread of the Screwl 17-and`are adapted to be engaged'by the. correspondingnends of :the sleeve 20. Thus. .when l'the-*sleeve 20 ymoves from the right ltozthe left its left end` .engages the erin =fi2wand 4 pushes fthe same and consequently shifts the rodxGO from the `right-.to the left to shi-ft thev double clutch 4member 5min. the'samefdirection vthereby engaging the clutchzmembers52 with theclutch members 50. l'When the sleeve 20 moves from `theleft to the right then its right-,hand end engages thearm Gland -pushes the Slatter, the

shifting rod 60 and the double clutch member 54 tothe right to disengage the clutch members 52 from the clutch members 50 and to engage .the clutch members 53 with the clutch members 51. It is understood that when ,the sleeve 2O engages the arm. 6,2 of

-the shifting rod 60 the wipers 25 andf26arc in left-handuposition on the glass plate 10,

and when the sleeve 20 engages the arms'Gl i then said Wipers are Ain right-handwendfp sition on fthe glass .plate 10.
